<!-- ========================= SAML NameID Generation ========================= -->
<!--
These generator lists handle NameID/Nameidentifier generation going forward. By default,
transient IDs for both SAML versions are enabled. The commented examples are for persistent IDs
and generating more one-off formats based on resolved attributes. The suggested approach is to
control their use via release of the underlying source attribute in the filter policy rather
than here, but you can set a property on any generator called "activationCondition" to limit
use in the most generic way.
Most of the relevant configuration settings are controlled using properties; an exception is
the generation of arbitrary/custom formats based on attribute information, examples of which
are shown below.
